Title: Improvements relating to the tuning of wireless receivers
IPC: H03J5/32
Filed: 1939-05-08
Abstract: 528,916. Wireless receiving sets. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. May 8, 1939, No. 13698. Convention date, May 6, 1938. [Class 40 (v)] Press button tuning equipment comprising press buttons and associated reactances is arranged in a separate box which may be mounted on the outside of the receiver cabinet. As shown the unit comprises a flat box K having press buttons D on the front and containing the associated reactances. The unit is arranged to be mounted below the cabinet E, the connections with the set being made through the normal ventilation holes in the underside of the cabinet. The connections may be made by plug and socket, and the alterations to the set circuits necessary when the unit is attached may be made by withdrawable plug contacts or by spring sets controlled by securing the unit to the cabinet. The press buttons are interlocking and the reactances may be adjusted when the unit is in position.

Title: Improvements in fog signalling and control of trains
IPC: B61L5/22
Filed: 1919-05-30
Abstract: 150,778. Thorrowgood, W. J., and Bushrod, F. May 30, 1919. Apparatus on train operated by explosion of detonator on rail.-The explosion of a detonator on the rails is caused to put in operation brake or whistle valves on one or more locomotives and indicators on locomotives, guards vans, or other vehicles. One or more pipes lead from a position near the detonator to a closed chamber having a flexible diaphragm which causes a pin, abutting thereon, to open or close an electric circuit including electro-magnets controlling valves or indicators or to release a latch from a weighted indicator arm which further serves to make or break the train-controlling circuit. A pipe may lead from near each front and rear wheel of a locomotive to a common diaphragm chamber, or each pipe may be connected to separate chambers, or they may be coupled in pairs. Fig. 1 shows the general arrangement of the apparatus. The pipe 5 conducts vibrations due to the explosion of a detonator to the chamber 6 controlling the electric circuit to an indicator magnet 34, bralce magnet 37. whistle magnet 40 on the first locomotive, similar magnets 42, 45, and 48 on a second locomotive and an indicator magnet 51 in a guard's van. The indicators on the locomotive remain set at danger until manually replaced by the driver raising the plunger 24 since the holding circuit passes through front contacts 21 on the armature 25 which also carries the flag 20. Fig. 9 shows an indicator which is normally held at clear by a detent 112 engaging the weighted arm 111. This detent is released by the raising of the rod 120 by the diaphragm of the penumatic chamber when a detonator is exploded, and the arm moves to the horizontal position and closes the contact 122 in the controlling circuit of the brake and other magnets. The switch operated by the explosion of the detonator is shown in Fig. 3a. A casing is supported on a flexible tube 7 in order to eliminatethe effect of vibrations of the vehicle on the switch. This casing is closed by a flexible diaphragm 63 secured by a metal ring 64. A pin 65 on a disk 66 which bears on this diaphragm abuts against the spring 11 which normally makes circuit with the contact 12 carried by the ring 64. When a detonator explodes the consequent disturbance on the diaphragm 63 moves the pin 65 against the stop 67 and breaks the circuit at the contacts 11, 12. The spring 68 assists in the return of the spring 11 to its normal position and tends to keep it there.

IPC: F25J3/04
Filed: 1955-05-12
Abstract: 780,822. Cold separation of gas mixtures. BRITISH OXYGEN CO., Ltd. May 2, 1956 [May 12, 1955], No. 13735/55. Class 8(2). In a compressed gas mixture e.g., air separation process wherein impurities e.g. water and carbon dioxide are condensed in reversible heat exchangers or in regenerators 1a, 1b, 2a, 2b, 3a and 3b cooled by components separated in a colunm 7 and having change-over valves (not shown), the balancing stream necessary to effect complete sublimation of the condensed impurities is provided by compressing at 11 a minor portion of the incoming air to a relatively high pressure, freeing it from condensible impurities, expanding isentropically at an engine 12 and adding to the cold air prior to entry into the column 7. In operation incoming air is divided into low and intermediate pressure portions viz. 2À6 and 4À8 atmospheres. The former is freed of condensibles in nitrogen regenerators 1a, 1b, and the latter is further divided into two streams which traverse nitrogen regenerators 2a, 2b and oxygen regenerators 3a, 3b. The cold low pressure air is further purified by washing with liquid air in the scrubber 4, the vapour from which is warmed in a heat exchanger 5 traversed by expanded high pressure air, expanded in a turbine 6 and joined by liquid from the scrubber 4 before being fed to the column 7 at an intermediate level thereof. The cold intermediate pressure air is purified by washing with liquid air from heat exchangers and the vapour traverses a condenser coil 9, and a subcooler 10 before being fed to the column 7 as reflux. Liquid air from scrubber 8 is fed to the scrubber 4.

Abstract: 514,643. Television. BAIRD TELEVISION, Ltd., and WILLANS, P. W. May 11, 1938, No. 14082. [Class 40 (iii)] One set of synchronising impulses is transmitted together with other intelligence, e.g., image signals on one carrier wave and the other set of synchronising impulses is transmitted on a second carrier wave. This second carrier wave may be .that used for transmitting the concomitant sound signals and if the line frequency signals are impressed on this carrier they may be arranged to periodically cut this carrier wave to zero and may lie within an amplitude range not occupied by the sound signal modulations to allow for amplitude filtering. Impulses of a multiple of the frequency of the line-synchronising pulses may be transmitted to give easier separation from the sound signals. Specification 386,849 is referred to.

[Class 44] [Also in Group VII] A releasable clasp for a wrist-watch ribbon or the like of the type comprising two separable parts, one end 4a of the ribbon being attached to one part 1 through a slot 3, while the other end 4b is threaded through two slots 5, 6 in the second part 2 which is such that the ribbon resists being pulled out, is characterised in that two integral spring ears 7 are turned down from the sides of the part 1, and preferably doubled inwards upon themselves, for releasably gripping the sides of the other part 2 when the two members are pressed together in superposed relationship. Preferably, shallow depressions on the upper surface of the part 2 guide the spring ears 7 into locating recesses in the sides of this part. To retain the ribbon 4b in place it is caused to bind in the slots 5, 6, which are therefore cut in inclined parts of the member 2 so that lips 10 are formed, which protrude downwards and distort the ribbon. The two plate members 1, 2 are formed from sheet metal by pressing or the like.

Abstract: 1417884 Quadraphonic systems MATSUSHITA ELECTRIC CORP OF AMERICA 23 March 1973 [7 April 1972] 14221/73 Heading H4L The four signals of a quadraphonic system in effect amplitude-modulate successive half-cycles of a composite (76 kHz) signal (Fig. 2, not shown) and are extracted by sampling each half-cycle at 25, 27, 29, 31. The sampling pulses are derived from a pilot frequency phase-lock loop 13-21 by binary dividers 19. The composite signal (Fig. 1 not shown) for compatible mono - stereo - quadraphonic transmission is formed from a first subcarrier (38 kHz) containing quadrature components carrying L and R information permitting stereo reception; a main channel (50 Hz-15 kHz) carrying the sum of L and R information for mono reception; a second subcarrier (76 kHz) carrying further front and rear components; and a pilot signal at 19 kHz. The receiver Fig. 3 demodulates the FM signal at 3 and locks a 304 kHz oscillator VCO 17 to the pilot signal by means of the phase lock loop 13, 15, 17, 19, 21. The binary divider 19 and decoder 23 produce the sampling pulses 25-31 on respective lines and these control gates 11 receiving the composite signal at 9.
